In a heavy control deck, you really shouldn't be losing jousts that often. It'll happen once in a while, though, and that's the worst case for the Gadgetzan Jouster. However, the Zombie Chow has the worst case of being a dead draw in the endgame when you can't afford to heal your opponent. I would think an endgame Chow draw happens more often and is more punishing than a lost joust for this card. Am I wrong?

So, for control decks that usually want a 1-of/possibly 2-of 1 drop that has good stats to keep tempo you usually run Zombie Chow, but now you at least have options. Not really sure what I'd prefer to run, maybe I'd prefer this though?

If you are making a "jousting" deck, as they put it, I don't think having a one drop on the deck would be good. In your starting hand it would be amazing though. (Maybe the same of a paladin holy wrath deck)
